Energy storage battery flame retardant

Are flame-retardant polymer electrolytes safe for lithium-ion batteries?

Flame-retardant polymer electrolytes have become indispensable in improving the safety of lithium-ion batteries and other energy storage systems. With the growing incidence of battery fires and explosions, these materials offer a promising solution to address the safety concerns associated with high-energy-density batteries.

How to achieve flame retardance for lithium battery?

Developing all-solid-state electrolytes, including inorganic ceramic/glass solid electrolytes, solid polymer electrolytes and composite organic/inorganic solid electrolytes, is another approach to achieve the key requirements of flame retardance for lithium battery.

Can flame retardants improve the performance of a battery?

Although adding flame retardants enhances fire resistance, it may negatively impact the SEI, resulting in degraded cycling performance. A promising alternative is grafting flame retardants onto polymer chains, which helps to minimize their adverse effects on the SEI and improves the electrochemical performance of the battery.

Can a flame retardant additive contact a liquid electrolyte?

The flame-retardant additive can effectively improve the flame retardance of polymer separators, but most flame-retardant additives cannot contact with the liquid electrolyte, otherwise the additives can increase the viscosity of liquid electrolyte or react with electrode materials during charges and discharges.

How can flame retardant polymer electrolytes improve the safety of Spes?

One influential strategy to improve the safety of SPEs is the use of flame-retardant polymer electrolytes (FRPEs) [, , , , , , , ]. By incorporating flame retardants into the polymer matrix, FRPEs can significantly reduce flammability, alter combustion behavior, and suppress thermal runaway .

Do hydrated materials affect the flame retardance of liquid electrolytes?

The hydrated materials have no negative effect on liquid electrolytes and can improve the flame retardance of liquid electrolytes. However, hydrated minerals can increase the hygroscopicity of separators and bring side reactions in LIBs at the same time. 3. Flame-retardant separators for all-solid-state lithium batteries
